To all whom it may concern.-

Be it known that I, SOLOMON R. Waco, a citizen of the United States of America, re-

siding atAppleton, in the county of Outagamie and .State of Wisconsin, have, invented certain new and useful Improvements in Refining-Engines, of which the following is a specification. I

This invention relates to certain new and useful improvements in refining-engines adapted to have assembled around the plug and around the interior of the shell groups of bars, at least one bar ineach group being of stone, and has for its objects an improved construction of the plug to adapt the bars to be readily secured in position thereon, to provide a novel manner of securing and arranging-the stone bars around the interior of. the

shell, to provide a novel construction and arrangement of bars around the plug of the engine, and to provide novel means for wedging the bars in position on the plug.

In addition to the above-stated broad objects of the invention minor objects relate to certain details of construction and to combinations and o erations of parts, all of which will be more 0 early apparent'from the specification to follow. I

That which I claim as my invention will be specifically indicated in the claims following the specification.

In order that my invention may be clearly understood, I have illustrated the same in th accompanying drawings, in which Figure 1 is a sectional elevation of the plug of a refining-engine constructed according to my invention. Fig. 2 is a cross-sectional view through the plug and shell of the engine. Fig. 3 is a plan view of a portion of the plug, showin the novel manner of arrangin a series of blades thereon. Fig. 4 is a deta' view of a ta -bolt, and Fig. 5 is a detail view of two we ges employed 1n securing the bars firmly in position between two ribs of the plug. I I

Referring now to the drawings, 1 indicates the shell, and "6 ti .o plug, of the engine. The shell is of the ordinary construction; The plug however, has a special construction, which will now be indicated.

3 indicates a series of rings extending around the plug at intervals, four of such rings being shown in the drawings.

4 indicates a series of ribs between which the bars -e assembled on the plug.

The rings 3 and the ribs 4 are preferably formed integral with the plu The plug as a whole is provided with sai rings and ribs by means, respectively, of a lathe and planer; but the manner of making the plug forms no part of this invention. The plug 2, as isusual in Jordan engines, is in the shape of a frustum of a cone, and a larger number of the ribs 4 are provided at the larger end of the plug than at the smaller, it beln understood, of course, that the ribs 4 are p aced at intervals, preferably e uidistant, around the Y entire circumference o the plug. The rings 3 are provided with undercut edges 5, forming recesses, and the outer sides of the rings are correspondingly inclined, the construction being such that the opposing edges of the rings'form annular pointed projections, which are adapted to fit correspondinglysha ed recesses 6, formed in the ends of the bla es assembled about the plug. The ribs 4, it will be noticed, do not extend from one ring to the other, but a suitable space is left between the ends of each rib and the adjacent rings, and this construction insures a ver much lighter plu than would be the case if the ribs extende the entire space between the respective rings, besides allowing the rings to be machine-finished.

It will be noted that between certain of the ribs I have shown a series of screw-threaded apertures 7, formed in the plug 2, and these apertures are for the purpose of receiving tapbolts 8, one of which is shown in detail in Fig. 4. These tap-bolts are for the purpose of supplying the plaoeof a rib 4, if for any reason more than the number of ribs provided should be re uired or desired in any particular section 0 the cone, or said tapbolts can be used entirely around the plug in place of ribs. The ribs 4, as shown in Fi 2, may be provided on opposite sides wit grooves 9, .each of which is adapted to receive a corresponding tongue 10, formed on the side of the blade adjacent tothe rib, and the tap-bolts 8 may be provided on opposite sides with corresponding grooves 11 for a similar purpose. In using the tap-boltstwo or more of such bolts would be employed and arranged in line to form a substitute for a rib.

In accordance with this invention I design to arrange a series of groups of bars between each two ribs of the plug, and each of these cups of bars may consist of one or more ars of a suitable material and a bar of stone. As shown in the drawings, each grou consists of two bars and an interposed er of stone. The outer bars of each group are in dicated by 12, and "these bars may be of metal or wood or of any other preferred material. The intermediate stone bar is 1nd1- cated by 13, and each of said bars may be rovided on one side with a tongue and on its opposite side with a corresponding groove 14, so that the various bars may mterlock when in osition on the plug, as clearly shown in Fig. 2. arated by means of interposed spacing-bars 15, of metal, wood, or any other preferred material, which may be. also provided with ton es and grooves corresponding to those on file cutting bars or. blades. It will be seen that this construction permits of great latitude in the distance apart at which the groups of blades are spaced around the plug and also in the thickness of blades employed, in the number of blades employed'in each group, and in the number of groups of blades arranged between any two ribs. Ingrouping the blades about the plug I provide for leaving a slight space betweenone of the ribs and the adjacent group of blades, and this space is adapted to receive the wedges 16,

(shown in detail in Fig.5,) which wedges, as

shown, have two 0 posing inclined faces 17, so that when one 0? position and the other wedge driven home the result will be. that the various cuttingbars and spacing-bars will be forced together and locke in position on the plug. Any open space may be filled with mo ten brimstone.

It is well known that thick bars do not produce asfine a quality of paper as thin bars,

while at the same time thick bars are desired for the initial treating of the stockas it enters the engine According to my invention, therefore, I providejrelatively thick bars at the smaller end of the plug, which of course is located at the'inlet end of the engine, andadually decrease the thickness of these ars, so that at the larger end ofjthe plug, where the stock leaves the engine, the bars will be relatively thin, and thus I secure the beneficial result of having thick bars for treating thecoarse stock as it enters the engine and thin bars-for finishing the stock as it leaves the engine. This construction and arrangement of the bars is clearly shown in Fig. 3.

In addition to decreasing the thickness of the bars as they approach the outlet/end of the engine it isv also an' object of my invention to rovide stone bars 13'of difierent degrees o finenessthat is to say, the stone bars at the'inlet end of the enginewill be of relatively coarse grain, the bars in the next section will be of finer grain, and the bars in the last section of still finer grain.

I may employ a single stone bar 13 between two metal bars 12, or I may provide between each pair of metal bars 12 a stone bar composed of several sections, and each of The groops of bars are septhe wedges is inserted in these sections will be of, successiv'el finer gigliln, beginning at the inlet end of t e mac e generic sense to cover natural stone or artic1al compositions resemblingstone. ,The

I employ'the word stone herein in a material which Iprefer to employ is carborundum. This is manufactured of va gdegrees of fineness, which are denote by lslitabie nlllimbersi1 asfNo. l2)0, No. 3%, No.40, c. ss own,t ere ore, yFig.3 eginning at the smaller end of the plug the first section ofthe stone blade between the metal.

blades 12 will be of No. 20 carborundrum, the next section of No. 30, and the next section of No. 40., In the next section of blades I will begin with No. 50- and continue throu h this and the succeeding sections successive y with Nos. 60, 70, 80, 90, and 100, No. 100 carborundrum being relatively very fine with respect to No. 20. I thus secure the advan tage of having a stone of coarse grain to Work on the coarse stock as it enters the machine and of having bars of successively less de 'grees of coarseness to work on the stock as it nears the finishing stage, while at the outlet end of the engine the plug is provided with stone bars of very fine grain to impart the necessa finish to the stock..

In or er to insure the free entrance of the stock into theengine and its rapid reduction, I find it advantageous to space the groups of bars at the smal er end of the plug at a comparatively great distance apart, while in the plug they are succeeding sections of the spaced at successively less distances apart. This construction is also shown by Fig. 3. The advantages resulting from this arrangement are thatthestock as it enters themachinev is comparatively hardto work, and thus a fewer number of blades are provided, requiring less horse-power er engine, but as the stock passes through t e machine it be comes more and more reduced, and the number of blades is correspondingly increased until the finishing end of the engine is reached, where the maximum number of blades is cmployed to finish the stock. This provides for the gradual reduction of the stock and, as stated, will result in a great saving of horsepower, while permittingthe engine to run at a high rate of speed and insuring the ultimate production of a very fine strong grade of paper.

Referring to the mannerof securin the bars about the plug, it will be seen that provide for their easy removal in caseit is re quired to renew any of the bars, as it is only necessary to knock the wedges 16 out of place, when all the bars or any one of them can'be readily removed.

' Referring to Fig. 2, I have illustrated the manner of arranging stone bars about the interior of the shell. B this construction I place at the sides of eac stone bar 18 wooden' bars 19 and I space the bars 18 the requisite distance apart by means of wedge-blocks 20, inserted between two wooden bars 19. The purpose of the wooden bars 19 is to prevent crumbling or breaking of the edges of the stone bars 18.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a refiningengine, a plug provided around its periphe with a series of longitudinally-disposed ribs, a series of blades inserted between the adjacent ribs, and a pair of wedges inserted in thespace between two ribs and having opposing inclined faces.

2. In a refining-engine, a plug provided around its periphery with a series of groups of two or more blades, one of said blades being of stone.

3. In a refining-engine, a plug provided around its periphery with a series of groups of blades, each group comprising one or more metal bars and a stone bar.

4. In a refining-engine, a plug provided around its periphe with a series of groups of three blades, the middle blade being of stone.

5. In a refining-engine, a plug having a series of bars thereon said bars gradually decreasing in thickness from one end of the plug toward the other.

6. In a refining-engine, a plug having a series of groups of two or more bars thereon one of said bars being of stone, said stone bars being of successively less degrees of coarseness from one end of the plug toward the other.

7. In a refining-engine, a plug having a series of groups of three bars thereon, the intermediate bar being of stone, said stone bar being of successively less degrees of coarseness from one end of the plug toward the other.

8. A refining-engine having its blades arranged in a series of groups of two or more bars, one of said bars being of stone, said stone bars being of successively less degrees of coarseness from one end of the engine toward the other.

9. In a refining-engine, a plug having a series of groups of two or more bars arranged thereon, one of said bars being composed of 5 sections of stone, the groups of bars extending from end to end of the plug and the stone sections being of successively less degrees of coarseness from one end of the plug toward the other.

10. A refining-engine having its blades arranged in a series of groups of three bars, the intermediate bar being composed of sections of stone, the groups of bars extending from end to end of the engine and the stone sections being of successivel less degrees of coarseness from one end 02 the plug toward the other. a

11. In a refining-engine, in combination with the plug having blades arranged there on, a shell having. a series of stone bars arranged around its interior, each of said stone bars having wooden bars at its sides, and a wedge-block inserted between successive pairs of wooden bars for spacing the stone bars the requisite distance apart.

12. A refining-engine having stone bars, said bars gradually decreasing in coarseness from one end of the engine toward the other.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
